Sirius 5
From Tardis Wiki, the free Doctor Who reference
Sirius V was a planet that contained the Academia Stellaris, considered by Romana II to be one of the greatest art galleries in Mutter's Spiral, though the Fourth Doctor considered the Louvre better. (TV: City of Death) The Prolocutor of the Babblesphere was copied onto a hard drive by the Fourth Doctor and donated to the Library of Artificial Intelligence in the Academia Stellaris on Sirius V. (AUDIO: Babblesphere)
